Write Register 0 Group
Figure 39.
The WR0 base register byte is identified by a 0 in bit 7 and any combi-
nation except 0, 0 in bits 0 and 1 (Figure 40). It sets the following condi-
tions.
Class of Operation
Bits 1 and 0 used together set the class of operation as sequential transfer
(0,1), search only (1,0), or sequential/transfer/search (1,1). Simultaneous
transfers or transfer/searches are obtained by selecting the search-only
class (1,0) and by allowing the external hardware to generate the appro-
priate bus control signals for the complete transfer (see the chapter
“Applications”).
